Links are the currency of the Web

Traffic on web nodes and pages are related directly to the relevance of the content, or simply to the number of links pointing to one particular Web page. The former model was used by the first generation of search engines, while the second one, based on link analysis independent of the content, is currently used by Google. With this in mind then we can say that web links have monetary value in the Web economy. Using this fact Boris Galitsky and Mark Levene from the School of Computer Science and Information Systems at Birkbeck College, University of London, have simulated an artificial world of Web links where you can buy and sell web links as a way to increase visibility, concluding that control of over links in the equilibrium state is polarized, as most agents end up with no resources to buy more links, in a classical example of the "rich get richer" phenomenon.
